Abstract

Grapes are one of the world’s healthiest foods and it is greatly nutritous. The current study was carried out to inspect the effect of gamma radiation on the surface microbiota of fresh green produce of one of the Pakistan’s most eaten variety Sundar khani grapes. The organoleptic characters and sensory attributes along with epiphytic microbial flora of both irradiated and control sample was analyzed after 7 days interval at refridgerated condition. For all trials , the decay assessment and results for sensory evaluation were recorded. Sensory attributes were maintained in low doses and teeth firmness and rachis browning was acceptable in grapes irradiated at 0.8 kGy. Positive effects of irradiation was increase in sweetness and flavor. Irradiation had no effect on berry shatter but weight loss and microbial load was significantly decreased in irradiated grapes.Results showed that low dose of 0.8 kGy was optimum dose at which quality of grapes was most acceptable and shelf life was increased by 2 weeks.
